Epic Hotel in Singapore
Crowne Plaza Changi Airport by IHG
Friendly staff on check in. There was a problem with the room and Josiah Gwee was excellent in dealing with the problem. Very much appreciated the complimentary dinner in the Allore restaurant as an apology. All good. I would stay at the Crowne Plaza again.

The rooms were clean and stocked with essential items. However, I wish we had complimentary water in the room. Overall, I enjoyed my stay.
